Abstract

La presente invención se refiere a un dispositivo sensorial (110) para registrar al menos una característica de un medio fluido (112), especialmente de un gas de escape de una máquina de combustión interna, que comprende al menos una carcasa de protección (114) para alojar al menos un elemento sensorial. Una carcasa interior (118) envuelve el elemento sensorial, estando envuelta la carcasa interior (118) al menos en parte por una carcasa exterior (116). Entre la carcasa interior (118) y la carcasa exterior (116) se forma un espacio intermedio (120), estando introducido en el espacio intermedio (120) al menos un componente cerámico (122). Según la invención, el componente cerámico (122) está presente al menos en parte en forma de un textil cerámico (124) poroso, alargable.The present invention relates to a sensory device (110) for recording at least one characteristic of a fluid medium (112), especially an exhaust gas of an internal combustion machine, comprising at least one protective housing (114) to house at least one sensory element. An inner shell (118) envelops the sensory element, the inner shell (118) being wrapped at least in part by an outer shell (116). Between the inner shell (118) and the outer shell (116) an intermediate space (120) is formed, at least one ceramic component (122) being inserted in the intermediate space (120). According to the invention, the ceramic component (122) is present at least in part in the form of a porous, elongated ceramic textile (124).
